Mrs P made punch and wanted to serve it in cone shaped cups. When she poured the drink into the cup she poured it to the top and still had some remaining in the bowl. Mrs P knew that she made 355ml of punch. The height of the cone shaped cup was 12cm and measured 8cm from one edge of the rim to the other.
a) Mrs P want to determine how much liquid her cone cup can hold? Round your answer to the nearest whole number
(hint:1ml=1cm^3)
so I did
v of cone=1/3TTr^2h
TT(4cm^2)(12cm)/3 =201cm^3=201 ml

B) how much punch is left over in the bowl?
355ml-201ml=154ml
Is this correct?
Thanks for checking my work
